What is a Generic Drug?

A generic drug is a copy of the brand-name drug with the same dosage, safety, strength, quality, consumption method, performance, and intended use. Before generics become available on the market, the generic company must prove it has the same active ingredients as the brand-name drug and works in the same way and in the same amount of time in the body.

The only differences between generics and their brand-name counterparts is that generics are less expensive and may look slightly different (eg. different shape or color), as trademarks laws prevent a generic from looking exactly like the brand-name drug.

Generics are less expensive because generic manufacturers don't have to invest large sums of money to develop a drug. When the brand-name patent expires, generic companies can manufacture a copy of the brand-name and sell it at a substantial discount.


Your healthcare provider may prescribe Razadyne to treat symptoms of dementia if you have Alzheimer's disease (AD).

Razadyne prevents symptoms of dementia like confusion, memory loss, and personality changes.

People with AD have a reduced amount of cholinergic-producing neurons in the brain. Razadyne is thought to work by increasing cholinergic action to reduce the long-term symptoms of dementia.
